Reactlit

Reactlit is a headless, procedural UI component for React inspired by Streamlit and modeled after Observable Framework.

Motivation

By writing your frontend procedurally you can treat your UI as functions that return data. This makes it easier to read and understand what the code is doing. Modern hook-based React has a lot of complexity: you have to know when to memoize, you have to follow the rules of hooks and declare their dependencies, you have to jump around in the code between the hooks at the top and the JSX where the data is used. Reactlit aims to to offer a simpler alternative to plain React for many common use cases.

Reactlit can't compete with the flexibility of React, but for many simpler use cases, it offers a higher-level abstraction that can result in code that is simpler and often shorter as well.

Getting Started

To get started with Reactlit, you can install the core package. We offer a set of pre-built input components in the @reactlit/vanilla and @reactlit/radix packages, or you can wrap your own components with the defineView helper.

npm install @reactlit/core @reactlit/radix

See the Getting Started guide for more information.
